“ 22,  Brainerd  and  Detroit,  Minnesota, 

“ 23,  Fargo,  Dakota,

“ 23,  Minneapolis  and  Lake  Minnetonka,  Minnesota. 

A few  other  localities  are  mentioned  in  the  list,  represented  by 
specimens  picked  up  at  points  where  the  train  stopped.  Species 
distributed  in  exsiccati  from  this  collection  are  so  noted. 

For  aid  in  the  determinations,  I am  indebted  to  Drs.  W.  G-. 
Farlow  and  P.  Magnus  and  especially  to  the  lamented  Dr.  Winter.

The  Minnesota  specimens  show  conidia  11.7-17^  by  13-21/x ; 
oospores  smooth  or  obscurely  roughened,  nearly  filling  the  oogon-

The  papilla  of  the  conidium  is  seen  with  difficulty  and  appears  more 
like  an  inward  thickening  of  the  wall  than  as  an  external  promi- 
nence. On  leaves  of  Ribes  hirtellum.  Detroit,  Minn.

Uromyces  Genistce-tinctor ice, (F.) , on  Trifolium ; Thompson  Falls, 
Mont.  Lupinus  argenteus ; Livingston,  Mont. 

This  is  the  same  as  U.  Lupini,  Sacc.,  and  is  characterized  by 
warty  apiculate  spores  with  fragile  pedicels.  U . Lupini , B.  & C. 
has  smooth  spores  and  is  very  different.  It  is  erroneously  referred 
here  by  Dr.  Winter  in  uDie  Pilze,”  i,  146,  on  the  authorit}7  of 
Thuemen,  Myc.  Univ.  842.  The  form  on  Trifolium  has  somewhat 
smaller  spores  but  is  not  specifically  distinct.

Uromyces  argophyllce,  Seymour,  in  Ell.  and  Ev.  N.  Am.  Fung.

Spots  none ; sori  amphigenous,  small,  scattered,  inconspicuous, 
obscured  by  the  hairs  of  the  leaf ; teleutospores  subglobose  to  ob- 
long, broadest  at,  above  or  below  the  middle,  17-25  X 22-45  y. ; 
epispore  thin,  of  uniform  thickness  or  slightly  thickened  and  pap- 
illate at  the  apex ; pedicel  fragile.  Differs  from  U.  Psoralece,  Pk. 
chiefly  in  longer  and  narrower  spores  and  more  deciduous  pedicels.

This  is  apparently  the  form  called  P.  rubefaciens , Johanson  ; 
see  Lagerheim  in  Hedw.  1889,  p.  106,  fig.  5.

commonly  seen  on  Galium,  concinnum  are  punctiform ; on  G. 
Aparine,  squarish  and  usually  remaining  covered  by  the  epidermis. 
The  uredospores  have  have  been  rarely  if  ever  found  in  the  United

In  the  original  specimens  described  by  Dr.  Winter  the  undevel- 
oped flowers  are  infested  before  the  expansion  of  the  inflorescence. 
In  these  specimens,  individual  flowers  of  the  fully  expanded  inflo- 
rescence are  affected.  The  spores  measure  9-10//.  This  has  been 
referred  to  Ustilago  Andropogonis , Kell,  and  Swingle  (Journ.  Myc. 
Vol.  v,  p.  12,  pi.  i,  figs.  12-26)  but  the  measurements  of  the  spores 
are  less  than  those  of  the  Kansas  specimens  as  there  stated,  also 


somewhat  less  than  those  given  by  Dr.  Winter  (Torr.Bull.  x,  7). 
The  spores  certainly  fall  apart  very  easily,  but  the  glomerules  may 
be  seen  by  careful  examination.  This  was  positively  stated  by

responsible  for  the  varietal  name.  ■
